A wheel rotates with a constasnt acceleration of `2.0rad/s^2`. If the wheel starts from rest, how many evolutions wil it make in the first 10 senconds?

Text Solution

Verified by Experts

The angular displacement in the first 10 seconds is ginven by
`theta=omega_0t+1/2alphat^2=1/2(2.0rad/s^2)(10s)^=10rad`.
As the whel turns by `2pi` radian in each revolution, the number of revolutions in 10 s is
`n=100/(2pi)=16`
